  NC controlled punching machines can be operated continuously unattended at night, etc., but in unmanned situations, the storage box cannot be replaced according to the material type. It was impossible to collect after sorting. Also, for recycling, it is desirable that the target scraps are sorted according to their materials.

  From the above, as shown in the above-mentioned patent document, it is desirable to move the sorting means such as a rotating shooter in accordance with the material of the scrap, and discharge the scrap to the corresponding collection box. . However, each apparatus has a problem that a large space is required for the collection box, and there is a problem that there is no solution when the collection box becomes full.

  SUMMARY OF THE INVENTION Accordingly, the present invention is to provide a separation and collection device that is space-saving and capable of sorting out scraps with certainty and that can cope with a full collection box.

  Accordingly, the present invention provides a waste receiving portion that opens upward in a trumpet shape that is moved by a moving means that moves to a disposal place for waste such as scraps discharged from a processing machine, A dropping hole that opens at the center bottom of the object receiving portion, a rotating shooter that is rotatably provided below the dropping hole, and changes the falling direction of the waste falling from the dropping hole in a predetermined direction, and the rotating shooter And a plurality of recovery areas that are equally disposed below the rotation shaft of the rotary shooter, and controls the drive means according to the type of waste, And a control means for moving the rotary shooter so that the waste falls in a collection area set according to the type.

  According to the invention with the above configuration, the waste transported by the moving means is received by the waste receiving portion and dropped into the dropping hole, and the waste is removed from the rotary shooter facing the predetermined collection box by the control means. Since it can discharge | release to a collection | recovery area | region, a waste can be collect | recovered to the collection | recovery area | region suitable for a material.

  In addition, it is desirable that the number of the collection areas corresponding to the type of material to be worked on the processing machine and at least one preliminary collection area are prepared, and the collection area and the preliminary collection area are independent collection boxes. It is desirable to be. In particular, when at least one of a plurality of recovery areas is set as a preliminary recovery box, and the recovery box set to fallen objects of a predetermined material becomes full, the rotating shooter is moved to the preliminary recovery box. Therefore, it is possible to avoid work stoppage due to the collection box becoming full.

  Further, the collection area is a plurality of collection spaces defined by walls around the rotary shooter, and the wall portions located between the collection spaces are movable walls that can move toward the collection space, respectively. It is desirable to comprise. As a result, the volume of the recovery space can be changed as necessary, so that it is possible to avoid work stoppage due to the recovery space becoming full.

  According to the present invention, since the installation space is small, the device of the present application can be installed as it is in the place where the conventional collection box was placed, and the rotation of the rotary shooter is small because it is a rotary motion. Since the recovery box can be easily moved by power and the recovery box can be installed around the rotation center of the rotary shooter, a plurality of recovery boxes can be efficiently arranged.

  In addition, since the rotary shooter is moved according to the type of waste such as scraps, another type of waste is stored in each of the collection boxes, so that there is an effect that separation is easy.

  Embodiments of the present invention will be described below with reference to the drawings.

  The sorting and collecting apparatus 1 according to the first embodiment of the present invention is arranged below the front end of a belt conveyor 2 as a moving device that transports waste (scrap) 3 generated from an NC punch processing machine body (not shown). As shown in FIGS. 1 and 2, a waste receiving portion 5 that opens in a trumpet shape toward the final end of the belt conveyor 2, a drop hole 6 that opens at the center bottom of the waste receiving portion 5, and this A rotating shooter 7 that is rotatably provided on the installation board 4 below the dropping hole 6 and changes the falling direction of the waste 3 falling from the dropping hole 6 to a predetermined direction, and a driving device that rotates the rotating shooter 7. 8 and a collection box 9 as a plurality of collection areas that are equally arranged below the rotation shaft of the rotary shooter 7, and controls the drive device 8 according to the type of the waste 3. , Waste 3 seeds In the waste collection box 9 that is determined to mount an said rotary chute 7 control device for moving (control unit C / U) 10 so as to fall by. The rotary shooter 7 includes an opening 70 communicating with the drop hole 8 and a slider 71 inclined at a predetermined angle in a predetermined direction.

  The waste receiver 5 is formed on a rotating ring 51 that is rotatable on the installation board 4 so that a plurality of panels 50 are combined so as to open upward in a trumpet shape to form an inverted truncated cone shape. The rotating ring 51 is fixed to a rotating board 52 that is rotatably provided on the installation board 4. The driving device 8 includes an electric motor 80 controlled by the control device 10, a pulley 81 fixed to the electric motor 80, and a driving belt 82 that rotates the pulley 81 and the rotating board 52. .

  The rotating ring 51 is provided with a position detecting terminal 53 for the position detecting sensor 11 for detecting the direction of the rotating shooter 7. Further, an overflow detection sensor 12 for detecting the amount of the waste 3 is provided above each collection box 9. Signals from the sensors 11 and 12 are transmitted to the control device 10. A signal from the position detection sensor 11 is input to the control device 10 as a theta direction signal PV, and a signal from the overflow detection sensor 12 is input to the control device 10 as an overflow signal EV. Furthermore, a material supply signal for supplying material to the NC punch machine main body (not shown) is input to the control device 10 as a waste material signal SP.

  In the first embodiment, four recovery boxes 9 are provided around the rotation center of the rotary shooter 7. There are three types of materials used in the NC punch processing machine, for example, a recovery box corresponding to iron, aluminum, and copper, and one preliminary recovery box, for example, as shown in FIGS. Thus, there are the recovery boxes 9A to 9C and the preliminary recovery box 9D.

  In the separation / collection apparatus 1 having the above configuration, the control device 10 operates the separation / collection apparatus 1 as shown in the flowchart of FIG. 3, for example. Hereinafter, the flowchart started from step 100 will be described.

  In step 110, a material signal SP relating to the material of the material provided to the NC punch machine (not shown) is input. In step 120, a shooter direction signal PV is input. In step 130, whether or not they are equal (SP = PV? ) Is determined. For example, when the material to be initially processed by the NC punching machine is iron, when the rotating shooter 7 does not face the collection box 9A in which the material is set to iron (when SP and PV are not equal), In step 140, the electric motor 80 is driven, and the rotary shooter 7 is rotated. Steps 110, 120, and 130 are repeated, and when SP and PV are equal to each other as determined in step 130 (when the rotating shooter 7 faces the recovery box 9A as shown in FIG. 4A), Proceeding to step 150, the rotation of the rotary shooter 7 is stopped. Thereby, iron scraps made of iron fall into the collection box 9A and are collected.

  On the other hand, if the overflow signal EV is input in step 160 and the overflow is not in an overflow state, the process returns to step 110 and the above-described operation is repeated.

  Further, when the processing material in the NC punching machine is changed from, for example, iron to aluminum, the material signal SP changes, so that the recovery box in which the material is set to aluminum, for example, the recovery box 9B shown in FIG. The above-described control is executed in the same manner so that the rotary shooter 7 is directed to the right side.

  Similarly, when the processing material in the NC punching machine is changed from, for example, aluminum to a cylinder, the material signal SP changes. Therefore, a collection box in which the material is set to the cylinder, for example, the collection box shown in FIG. The above-described control is similarly performed so that the rotary shooter 7 faces 9C.

  The above operation can be repeated overnight in an unattended state. However, if there is a bias in the product material, the amount of scrap collected in one collection box increases, and when the collection box is full, an overflow of the collection box is detected. In this case, since the overflow is determined in the determination in step 170, the process proceeds to step 180, and the rotating shooter 7 is driven (rotated), thereby the preliminary recovery box shown in FIG. 4D, for example, from the recovery boxes 9A to 9C. Go to the collection box 9D set to. Accordingly, when it is determined in step 190 that the rotary shooter 7 has been directed to the collection box 9D, the process proceeds to step 200, where the drive of the rotary shooter 7 is stopped, and the position of the rotary shooter 7 is as shown in FIG. ).

  Normally, it is possible to operate unattended all night by providing this preliminary collection box, but when the preliminary collection box is full, the NC punch processing machine is stopped and the recovery box is replaced. In order to do so, an alarm may be issued to call an attendant.

  5A to 5D, the recovery box 9 according to the second embodiment includes recovery areas 9A 'to 9D' defined by the wall 90. As shown in FIG. 5A, the wall portion 90 is characterized by providing a pair of movable walls 91 and 92 that can be opened and closed on each side.

  For example, when it is desired to enlarge the collection area 9A ′, as shown in FIG. 5B, the movable walls 91B and 92B on the collection area 9B ′ side are moved so as to define a small space 9E on the collection area 9B ′ side. Similarly, the movable walls 91D and 92D on the collection space 9D ′ side are moved so as to define the small space 9F on the collection area 9D ′ side. Then, as shown in FIG. 5C, the movable wall 91A on the collection area 9A ′ side is moved so as to be aligned with the movable wall 92B, and at the same time, the movable wall 92A on the collection area 9A ′ side is moved to the movable wall 92D. As shown in FIG. 5D, a large collection area 9G can be formed. Thereby, the collection areas 9A ', 9B', 9C ', 9D' are changed to the small collection areas 9E, 9F, the medium collection area 9C ', and the large collection area 9G.

  In this manner, various combinations of recovery spaces can be formed by freely moving the movable walls 92 and 92.
